I bought 2x donkey tails plants. I Saw leaves got black brown spots and they get so mussy and easy to come off when they turn black/brown. Some turned white and dry. Stems also getting dry. Pls look at the image and let me know if i can save my plant anyway. I am thinking to repot the whole 2 hanging baskets.

I'm not able to get a good look at the soil, but this looks like a fungal infection. This can be caused by overwatering, or just sitting in water for too long, or it can be present in soil before it is planted.
I would suggest replacing 1/3 of the water, that you use to give it a drink, with peroxide. This will kill off anything in the soil, and as long as the plant isn't too far infected, then it will help the plant to clear itself up.
